JOHN F. SLOAN, OF PEORIA, ILLINOIS.

AUTOMOBILE.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed February 12, 1912. Serial No. 676,977.

To all whom it may concern:

Be it known that I, JOHN F. SLoAN, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Automobiles, of which the following is a specification.

My invention relates to improvements in automobiles.

More particularly, my invention relates to means for maintaining heat, and hence circulation of the water in the water circulating system associated with water cooled motors in automobiles.

It is my purpose to introduce a water heatv ing unit in the circulatory system, as distinguished from the application of heat, as by flame or jet, applied to the outside surface or inclosing tubes or means for -said systems.

The destructive effect of freezing the water within the water circulating systems of automobiles is too well known to need to be pointed out, and as my invention may be applied to keep the water within the circulating system warm, it is.obvi0us that it will prevent freezing.

The disadvantage attending the starting of an engine when the water in the circulating system is cold, either by hand or other power, is also well known. My invention is adapted to keep the water warm and willperpetually maintain the engine cylinders in condition to facilitate ready explosion and consequent easy starting.

My invention has application to all circulating systems for water cooled engines, 'whether pumps are employed or not.

Referring to the drawings, Figure 1 is a side elevation of automobile engine parts showing my invention in association therewith; Fig. 2 is an enlarged view of certain engine parts showing particularly the water cilrcglating system with my invention app 1e -Referring more particularly to the drawings, 2 refers to water jackets inclosing the engine cylinders; 3 refers to the radiator.

4 refers to the pipe communicating with the water jackets 2 and with the radiator 3 above the water jackets.

5, 6 and 7 refer to lead pipes to pump 8.

9 is a connecting pipe between radiator 3 and pipe 10 which communicates with the P P- The parts which have just above been referred to are the usual and ordinary parts existing in an automobile, including a pump,

which I shall assume when at rest will permit passage of water therethrough, it is my design to introduce into the water contained within the circulating system, a heating unit whereby the latter may be heated.

In the form in which I have shown my invention, I have included a pump and a by pass around the same so that the pump may be 'cut out of the system. and I have shown a special connection with the by-pass whereby the heating unit may be introduced into the circulating system. Referring particularly to this part just mentioned, 11, 12 and 13 are pipes constituting the by-pass arrangement within which I have included the valve 14, whereby water may be permitted to flow through the by-pass or may be cut off from such flow therethrough.

15 is a water containing receptacle which may be in any form desired, but as I have shown it. it is substantially a rectangular, elongated box communicating respectively at top and bottom with pipes 12 and 13. The capacity of the water box is such that an electric heater 16 having a considerable surface exposure is carried therein, the heater substantially dividing said box into upper and lower sections, and the water box and heater extending horizontally with respect to some vertical pipe or pipes of the system, as 13. The course of the water then, after entering the box 15, is horizontally along the bottom of the box. below the heater surface, where it is gradually heated to a certain degree, and then back along the top of the heater 16, to receive its full degree of heat, and then out at the pipe 13. As it requires but a small amount of heat to cause movement or circulation of water, only a small amount of heat isneeded to effect the purpose of heating the water in the system to a sui'liciently high temperature to keep the cylinders of the engines warm.

In practice, the by-pass may be cut out in case circulation may be obtained through the pump, and in that case the heater 15 may be associated directly with the pipe system, as for instance, with pipe 10, thus heating and attendant circulation of the Water in the system will be obtained. In practice, the electric current or other heat source may be applied externally of the automobile, that is from some fixed established supply or it may be applied from batteries carried in the vehicle or other heat source carried thereby. 1

I do not desire to limit the application of my invention either in form or in any particular adaptation. I say generally that it may be utilized at any and all times that heat, independent of the motor may be of advantage for the purpose, that is, by carrying the heat supply Whether it be from batteries or otherwise, in connection with the motor. It may be cut in for continuous application to promote heating of the Water or when so carried it may be cut in or out at any time desired. It may be utilized at the place where the automobile is housed by simply making a connection with a permanent electric or other heat source.

IVhat I claim is:

1. A cooling system for automobiles and the like, comprising in combination, a radiator, a water jacket, a supply pipe'from the the pump with its ends communicating with the supply pipe, a heating box in the'by-pass and a heating element within the heating box for direct contact with the fluid passing through the bypass.

In testimony whereof I have affixed my signature in presence of two witnesses.
